Brittany Maynard , the terminally ill woman who plans to take her own life , has checked the last item off her bucket list .

She visited the Grand Canyon last week .

`` The Canyon was breathtakingly beautiful , '' she wrote on her website , `` and I was able to enjoy my time with the two things I love most : my family and nature . ''

Photos showed her and her husband standing on the edge of the canyon , hugging and kissing .

But her cancer reasserted itself .

`` Severe headaches and neck pain are never far away , and unfortunately the next morning I had my worst seizure thus far , '' she wrote on her website . `` My speech was paralyzed for quite a while after I regained consciousness , and the feeling of fatigue continued for the rest of the day . ''

Maynard , 29 , had been married a year when she discovered she had an aggressive brain cancer .

Last April , doctors said she had six months to live . She considered dying in a hospice , she wrote in an op-ed piece for CNN .

`` I quickly decided that death with dignity was the best option for me and my family , '' she wrote for CNN . `` We had to uproot from California to Oregon , because Oregon is one of only five states where death with dignity is authorized . ''

Maynard posted YouTube videos in which she and family members talked about her decision and supported an expansion of assisted suicide laws . She supports an organization , Compassion and Choices , to promote that idea .

`` My dream is that every terminally ill American has access to the choice to die on their own terms with dignity , '' she wrote on her website .
